2 Claims. (Cl. 248-231) This invention relates to an improvement in pole band fittings for the attachment of guy wires to wood poles used on electrical power distribution lines. Wood provides a natural dielectric which has never been equaled by any other practical material that might be used to make poles. However, wood poles are used as nature made them, of varying shapes, sizes, and irregularities. Often it is dilficult to find a smooth section on the surface where a rigid pole band can be fit. The impossibility of standardizing the cross-sectional dimensions is another factor that makes a rigid pole band unusable on many poles.

When stress from the guy wires is distributed unevenly on the guying anchor, it could cut into the pole and mar the surface as well as weaken the pole. Or, the uneven stress, if continued too long in one direction, could cause the poles to lean angularly with subsequent strain and ripping of the wires and insulators.

The need is acute for a pole band which meets the above conditions, and so to meet this need, I offer this invention.

This invention relates to an improvement in pole bands for the attachment of guy wires and has for its principal object to provide a pole band which is strong and flexible solthat it can be adapted to Various sized and shaped p0 es.

Another object is to provide a pole band which distributes the stress evenly around the pole.

Other objects will appear from time to time in the course of the specification and claims.

An embodiment of my invention is illustrated in the accompanying drawing in which:

Fig. 1 is a horizontal sectional view through the pole above the pole band.

Fig. 2 is a side view of the pole band taken from the side of Fig. 1.

Fig. 3 is an enlarged detail of one of the loops of the cable flex plate.

The pole bands in use at present are made of heavy steel bands in two, three, or four sections clamped together by bolts. They are heavy and awkward to handle and are limited to use on poles of the exact size as the band. There is a real need for pole bands that are flexible both in diameter and in shape. To fill this need this invention has been developed to provide a pole band made of high strength steel cables.

In Fig. 1 it can be seen that my pole band is divided into three sections 1, 2 and 3. At two of the intersec tions the connecting means 4 provides loops 5 for attaching the guy wires. Projections 5a on the loops 5 from a retaining means for the locking rings 15 which are clipped around the loops 5 to prevent them from spreading The third intersection 6 provides tightening means 7 so that the band can be drawn tightly around the pole. Each section 1, 2 and 3 has one or more flexible cables 8. In Fig. 2 I show four cables. The ends of the cables are swaged into a tubular ferrule member 9 with a threaded end to which a nut 10 is screwed to secure the cable to the intersectional connecting means 4 and 6. Various length cables can be kept in stock and the desired length can then be inserted into and screwed to the connecting means in order to make pole bands of any desired diameter.

The loops 5 as illustrated are U-shaped and are directed outwardly and the legs of the loops are extended in the form of apertured flanges 5 which extend outwardly from the legs in angular relation thereto. Also the tlghtening or take-up members 7 each include an apertured flange 7 and an apertured lug 7 and a belt 7 extends through the apertures in the lugs. The ferrules 9 extend through the apertures in all of the flanges and the nuts 10 which are engaged with the threaded ends of the ferrules engage the inner walls of the flanges.

An optional feature of this pole band is provided in the use of the cable flexing pole plate 11 which can be used to prevent the cables from biting into the poles. These pole plates are formed from a flat piece of steel as shown in Fig. 3. Slotted tongues 12 are cut and bent upward from the steel plate and the flexible steel cables 8 are then threaded through these slotted tongues 12. The cable flexing pole plate 11 is shown as being threaded on cable section 3 of Fig. 1. This feature also guys or locates the cables as well as distributing the stresses.

Thus, it can be seen that with my cable flexing pole band, a pole band is provided of strength and flexibility which can be adjusted to various sizes and shapes of poles. This improved hand does not chafe or mar the surface and structure of the wood pole. It is easily adaptable to various contours and cross-sectional widths and is stronger than the usual type band.

While one preferred embodiment of the invention has been described, it is only to be limited by the clear import of the following claims.

I claim:

1. A pole band for the anchoring of corresponding ends of guy wire to a pole; comprising a pair of pole engageable members each of which includes an outwardly directed U-shaped loop for attachment of an end of a guy wire, flanges projecting outwardly from the legs of said loops in angular relation thereto and each being provided with a plurality of apertures, the said legs of the loops being provided with lateral projections, a ring encircling the legs of each loop for retaining same against spreading and being retained in operative position adjacent said flanges by said projections, a pair of take-up members each having an outwardly directed flange provided with a plurality of apertures and an apertured lug, the lugs being on adjacent ends of the take-up members, a bolt extending through the apertures in said lugs and provided with a nut externally engaging one of the lugs, a plurality. of groups of cable sections with the sections of each group spaced axially of the band, each of the cable sections being provided with a tubular ferrule on each end thereof and which ferrules have externally threaded ends, the ferrules of one group of cable sections extending through the apertures in adjacent flanges of the pole engaging members, and having nuts applied thereto, the ferrules on corresponding ends of the cables of the other groups thereof extending through the apertures in the other flanges of the pole engaging members, and having nuts applied thereto, and the ferrules on the other ends of said last cables extending through the apertures in the flanges of the take-up members and having nuts applied thereto.

2. The structure according to claim 1, together with a plate for disposal between the pole and the cables of at least one group thereof, said plate comprising a relatively thin steel sheet having a plurality of slotted tongues bent outwardly therefrom in laterally spaced relation in conformity with the spacing of the cable sections for passage of the cable sections through the slots in the tongues.
